Section 21: Regulatory traffic signs This section includes the signs that show a road regulation is in place. These must be obeyed. Regulatory signs show the course a driver must follow and an action they are required to take or forbidden to take. They are usually circular and have a red border and black symbols or letters on a white background. Mandatory regulatory signs that indicate the direction traffic must take at junctions are blue and white. Stop Yield Yield School wardens stop sign No left turn No entry or No straight No right turn Parking prohibited Clearway Max speed limit 30kmh Max speed limit 50kmh Max speed limit 60kmh Max speed limit 80kmh Max speed limit 100kmh Max speed limit 120kmh 213
The following is an alternative design for the 80kmh speed limit sign. This sign may be provided: on a local road to indicate that a speed limit of 80kmh applies; or at a location where special speed limit bye-laws specify that the special speed limit of 80kmh applies in respect of a local road or part of a local road in a built-up area. Max speed limit 80kmh Speed limits per lane No bicycles No ridden or accompanied horses No entry to vehicles Maximum gross weight (traffic management) Maximum vehicle length Maximum vehicle width Maximum axle weight No overtaking for three-axle vehicles No horse carriages Height restriction 214
